 a species of West Indian oyster (Ostrea from, L.) which 

 attaches itself to twigs. 



Professor Poultom remarked that both this and the Cocci- 

 nellid exhibited by Mr. Bennett were probably cases of 

 accidental resemblance. 



Rhodbsian [nseots as Pkky. — Professor K. B. Poulton 

 exhibited the following specimens sent t<> him by Mi\ ' '. I'. M. 

 Swynnerton, both of which had been captured on the outskirts 

 (3,800 ft.) of Chirinda I l tzaland, B.B. Rhodesia.

 I. September 8, 1911, by one of his native collectors 

 from a M'lanje Bulbul (PhyUostrephiu milcnyensis). The head 

 was wanting, and there were symmetrical injuries at the anal 

 angle of the hind wings similar to those so often seen in living 

 butterflies. 



2. Two wings of Pn lis archesia, <>., • . and the fragments 

 of a Blattid, probably of the genus Deropeltis, taken dime 25,

latter had been attacked in the manner characteristic of a 



largish Bpider. The butterfly had probably sheltered in the 



thatch to which the Web was fixed.

doing BO, and reading Mr. Moulton's account of them, he 



wished to acknowledge the hind help he bad received from 

 Mr. t '. d. Gahan, who had compared several of the Coleoptera 

 with the types, and had described one new species of DopAwta, 

 and also the kind assistance rendered to him by Sir George 

 Sampson. He then communicated the following paper by

"Among some recent additions to the insect collections in 

 the Sarawak Museum, 1 noticed certain curious species which,

 different families, afforded excellent examples illustrating the 

 theory of mimicry, As some of these new captures prove to
